Background: Radiofrequency ablation (RFA) is an effective treatment for hepatocellular carcinoma (HCC). However, rare but serious complications may occur after RFA. We describe a case of diaphragmatic hernia associated with RFA. Case Presentation: A 68-year-old man with a history of hepatitis C-related liver cirrhosis was admitted to our hospital because of lower abdominal pain. Three years earlier, he underwent RFA for HCC in segment 8. Computed tomography revealed that the intestine was intruding into the right thoracic cavity through a diaphragmatic hernia. On the basis of the diagnosis of right diaphragmatic hernia with a strangulated ileus, an emergency operation was performed. Perforation of the strangulated transverse colon into the right thoracic cavity was suspected, and a combined approach of laparotomy and thoracotomy was utilized. The operative findings showed that the diaphragmatic hernia was 3.5 × 2.0 cm in diameter, and it was simply sutured with a nonabsorbable suture material. Resection of the intruded ischemic transverse colon was completed, and a covering ileostomy was performed. The patient was discharged without any complications. Conclusions: RFA is widely used for the treatment of HCC. Reports of early- and late-phase complications indicate that heat damage contributes to the fragility of neighboring organs. The occurrence of diaphragmatic hernia after RFA is one of the delayed complications. Although it rarely occurs, this complication requires emergency surgery. In conclusion, if perforation of the intestine into the thoracic cavity is suspected, thoracolaparotomy should be considered as a treatment option to prevent postoperative massive empyema.

We applied adaptive dynamics to double slit interference phenomenon using particle model and obtained partial successful results in our previous report. The patterns qualitatively corresponded well with experiments. Several properties such as concave single slit pattern and large influence of slight displacement of the emission position were different from the experimental results. In this study we tried other slit conditions and obtained consistent patterns with experiments. We do not claim that the adaptive dynamics is the principle of quantum mechanics, but the present results support the probability of adaptive dynamics as the candidate of the basis of quantum mechanics. We discuss the advantages of the adaptive dynamical view for foundations of quantum mechanics.

The ultracontractivity is well studied and several equivalent conditions are known. In this paper, we introduce the dual notion of the ultracontractivity, which we call the dual ultracontractivity. We give necessary and sufficient conditions for the dual ultracontractivity. As an application, we discuss one-dimensional diffusion processes. We can write the conditions for the dual ultracontractivity in terms of speed measures.
